ORMESHER, OF CINCINNATI, OHIO, ASSIGNORS TO CE1/IROC', INC., 0F CINCINNATI, OHIO, A CORPORATION OF OHIO CERAMIC MACHINE Application led May 11, 1928.

Our invention relates to machines for manufacturing building material, and, in particular, building units of H-shape of concrete, ceramic materials and the like.

It is the object of our invention to provide a machine in which the movable mold box or die superimposed upon a pallet may be filled with plastic material to Which a die is ap plied under predetermined pressure, such pressure being gradually applied to permit of the material settling, and, thereafter, the die and punch are removed from the molded material to permit of the removal of the pallet with the molded products thereon.

In particular, it is our object to provide this form of pressure punch Within the movable die in order to gradually apply pressure to consolidate the material to form it in the desired shape and to so condense and compress it that it Will stay in its molded form immediately upon the removal of the mold, die and punch.

It is our object to eliminate pounding, tamping and ramming or the necessity for holding the material in its mold or under pressure for any appreciable time so that quantity production with the minimum of vibration in the machine can be secured.

Referring to the drawings in detail, 1 refers to upright steel corner posts at each corner of the machine forming a rectangular supporting structure. Reinforcing plates 2 are mounted on these` vertical corner posts and on the horizontal front and rear transverse connecting plates 3 and 4. Connecting bolts 5 connect these fore and aft members and the uprights at the corners. Thus, a rigid steel frame structure is provided. This structure is connected at its top by the transverse front and rear members 6 and 7 and the fore and aft top members 8 and 9. These members are connected together at their corners by reinforcing corner plates 10. i

In the lower part of the machine, there is mounted a transverse horizontal platform member 11 for supporting the removable pallet 12 which has the legs 13 extending on either side of the platform 11. This platform rests upon the transverse members 3 and 4. To the platform is connected the side guide rods 14 and 15. The side guide rods 14 and 15 serve to guide the mold die box 16 which is connected to the rods 14 through the cor-` ner plates 17, straps 18 and eyes 19 which slide on the rods 14 and 15. These eyes 19 are engaged by a strap 2O to which is pivoted at 21 the strip link 22 that serves to elevate the mold box a short distance to strip the parts from the molded products Whichare molded in it. The die box 1G has a track 23 connected thereto on the top edges thereof on the sidefor guiding the Wheels 24 which engaged by the gearrollers 95 and 96 which are adapted to reciprocate radially in slots 97 with Vshafts 98 in the gears 37 and 99. Springs 100 in such gears tend to thrust the shafts and rollers radially of the gears. Mounted on the shaft 39 are spaced cams 101 which engage at intervals with the rollers 95 and 96 which in turn engage the rollers and 94 moving the roller shaft 92 transversely and thereby shifting the clutch 86 and the companion clutch 102 which is adapted through its face 103 to engage with the clutch face 104 of the gear 99 and thereby causing actuation of the load mechanism hereinafter described. Each of the clutches 86 and 102 are provided with similar faces 105 engaging with the surfaces 106.

`Loading mechanism The loading mechanism is operated through the gear 99 on the shaft 107. This shaft 107 carries an arm 108 pivoted at 109 to the arm 110 which in turn is mounted pivotally on the crank 111 fastened to the shaft 112. Connected to `this shaft 112 are a pair of spaced depending loading arms 113. These arms are provided with slots 114 at their lower ends which engage with the outside of the axle 115 of the wheels 24 on the rim of theloading hopper`25. The movement forwardly of these arms serve to move the loading hopper on its Wheels 24 on the track 23 to load the mold box.

Hopper mechanism vwithdrawn position, is sealed by the bottom 4G.' of the platform designated 117. The top of the hopper is open at 118 and registers with theopen mouth of the chute 119 which is carried in the frame work 120 that is suspended from the rear of the machine frame. This chute 119 is connected to a supply box or chute 121. The hopper box reciprocates beneath the chute 119. As it is.` necessary to cut off the chute 119 to stop the flow of concrete into the hopper box 25 whenthe hopper box is moved forwardly into delivery position, we provide a sliding cut off 122 which Y slides in the side guides 123. This slide cut off is adapted to pass through the opening 124 in the rear wall of the chute 119. The

slide cut-off 122 is provided with a depending lug ,125 which is connected by the hook 126 on the back of the hopper box 25. Guide rollers 127 are connect-ed to the box in the bottom of the slide 123 to guidethe parts relative to one another.

The arm 126 carries a lug 138 that is attached by the spring 140 to the hopper box 25 so that the hook is always held in engaging position with the lug 125. The roller 127 carried on the end of the member 126 is adapted to engage with the lug 141 carried on the frame 123 which serves to unlock the member 126 from the lug 125 to allow the slide to re main in its closed position while the hopper box 25 moves over the mold box to discharge its contents. Connected to the depending arms 113 is a bell crank composed of the arms 128 and 129 pivoted at 130. The lower end of the arm 129 is connected to the stirrer shaft 131 carrying the blades 132 to stir the contents of the hopper box and distribute the contents in the mold box.

An alternate form of this apparatus is shown in Figure 14 where the rack bar 133 is substituted for the bell crank. One end of the bar is free and the other is pivoted to the arm 113. The rack is maintained in engage ment with the pinion by the roller 136 carried on the arm 137 mounted on the shaft 131. Thus, as the filler box reciprocates its contents is stirred and distributed.

In order to hold the mold box in its lower position, we provide a locking mechanism consisting of a lever mounted on the shaft 33, such lever being designated 142. This lever actuates a pitman 142@ that in turn moves a lever 143 pivotally mounted at 144 on the frame of the machine. This lever' is connected to a pitman 145 that controls a locking latch 146 that is adapted to engage with a locking shoulder 147 on the link 22.

Method of operation When the handle 46 is pulled the clutch faces 44 and 45 are engaged and the line of power through the shaft 42, gear 41, gear 40 and shaft 39 is established. This results in the driving of the pinion 38 and the rotating of the gears 37 and 99. The parts are so arranged that this rotation will shift the clutch 102 to engage the gear 99 causing the shaft 107 to rotate. This results in the actuation of the actuating hopper box arms 113 so that the hopper is moved over the mold box, the bottom of which is closed by the new pallet12 filling the mold box and restoring the hopper to its initial position `Where the concrete in the chute 119 refills the box by `reason of the withdrawal of the closing slide 122.

As soon as this operation has been completed the cams 101 will have engaged with the rollers 96 and shifted the clutch lever so that the clutch 102 is disengaged from the gear 99 and the clutch 86 is engaged with the gear 37 thereby actuating the shaft 36 which causes the punch or pressing member to dcscend into the mold box.

As the toggle links 77 and 78 pass over dead center about a ton of pressure is gradually applied to the concrete expelling surplus moisture and forming it into a solid mass.

When the parts are in this position the pressing or punch members are left in this pressing :position for a brief inter'val'because -as the toggles 77 and 7 8 start to return in their cycle of operations to lift the pressing` punch, the punch not operated due to theV loose joint or slot 76a. While the punch is` remaining stationary and undisturbed dur! ing this brief interval the cams are moved:

into position to engage the roller 3% and actuate the bell crank arms 32 and 31 which, in turn, lift the links 22 and cause the mold'boil and molds to be stripped from the molded products on tlie pallet, atwliich time the operator can remove the palletjbeiore the weight ofy the mold box causes itsreturn on to a new pallet Which has been'reinsertedy due to thepassage of thecam 35 by the roller 84e As 'soon as the stripping action has been accomplished the toggle members Z 7 and Z8 will have again piclred up the punch orpressing mechanism and elevated it to its initial elevated position and when that position has been accomplished the clutch t and l5 will have been declutched by the operation oic the cams 59 and 60 on the cani nose 6l ot 'Ll e lever 57 whichicontrols shifting yoliek 53 and the yoke 54. Tlieinacliine then to rest.
